Survey data were analyzed using descriptive statistics, and interview results with thematic analysis. \u0000Results: There was considerable variability in endoscopy training practices between teaching hospitals in the structure of endoscopy supervision, the criteria used to determine the level of supervision, and the participation of trainers in endoscopy teaching courses. Interview participants agreed that an endoscopy training supervisor requires several teaching strategies, highlighting the importance of formal education in endoscopy teaching. Interview participants perceived self-regulated learning strategies as essential for residents to learn endoscopy effectively. The perceived main barriers to effective supervision were a lack of time and heavy workload. Participants expressed the desire for more standardization in endoscopy training programs between teaching hospitals. \u0000Conclusions: Considerable variability in endoscopy training practices between gastroenterology teaching hospitals was identified. Formal education on endoscopy teaching, promotion of self-regulated learning, and standardization of endoscopy training programs and supervision practices have the potential to improve future endoscopy training.","PeriodicalId":508938,"journal":{"name":"Endoscopy International Open","volume":"51 29","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141805054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relationship between Pure cut, Endocut, post-ERCP pancreatitis (PEP) and bleeding is unclear. This systematic review and meta-analysis compares these two current types and their relationships with adverse events.\u0000Methods: This systematic review involved searching articles in multiple databases until August 2023 comparing pure cut versus Endocut in biliary sphincterotomy. The meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA).\u0000Results: A total of 987 patients from four randomized controlled trials were included. Overall pancreatitis: a higher risk of pancreatitis was found in the Endocut group than in the pure cut group (P=0.001, RD=0,04 [0.01,0.06]; I2=29%). Overall immediate bleeding: statistical significance was found to favour Endocut, (P=0.05; RD=-0.15 [-0.29, -0.00]; I2=93%).

However, its impact on gut hormones and their relationship with weight loss remains unknown. Patients and Methods: This is a substudy of a previous randomized clinical trial. Adults with significant weight regain and dilated gastrojejunostomy underwent TORe with Argon Plasma Coagulation (APC) alone or APC plus endoscopic suturing (APC-Suture). Serum levels of ghrelin, GLP-1, and PYY were assessed at fasting, 30, 60, 90, and 120 minutes after a standardized liquid meal. Results were compared according to allocation group, clinical success, and history of cholecystectomy. Results: Thirty-six patients (19 APC vs. 17 APC-Suture) were enrolled. There were no significant baseline differences between groups. In all analyses, the typical postprandial decrease in ghrelin levels was delayed by 30 minutes, but no other changes were noted. GLP-1 levels significantly decreased at 12 months in both allocation groups. Similar findings were noted after dividing groups according to the history of cholecystectomy and clinical success. The APC cohort presented an increase in PYY levels at 90 minutes, while APC-Suture did not. Naïve patients had significantly lower PYY levels at baseline (p=0.01) compared to cholecystectomized individuals. This latter group experienced a significant increase in the AUC for PYY levels, while naïve patients did not, leading to a higher AUC at 12 months (p=0.0001).

This is especially because standard oximetric monitors display only hypoxia and not the preceding hypercapnia. Therefore, the question arises whether use of a nasal positive airway pressure (nPAP) system can decrease the rate of sedation-associated events.\u0000Patients and methods: A randomized, prospective trial was conducted at University Hospital Ulm, including 98 consecutive patients, identified as high-risk (American Society of Anesthesiologists physical status ≥ 3) and scheduled for prolonged (> 15 minutes) endoscopic procedures. Patients underwent 1:1 randomization to two groups: interventional (nPAP-Mask) and control (conventional oxygen supplementation). Levels of CO2 were measured noninvasively by transcutaneous capnometry device. The primary outcome was incidence of hypoxia (SpO2 < 90% over 10 seconds) and incidence of severe hypoxia was incidence of SpO2< 80% over 10 seconds. One of our secondary objectives was to determine if the nPAP-Mask could result in significant CO2 retention among high-risk patients.\u0000Results: Data analysis showed lower incidence of hypoxia in the interventional group (10/47 vs. 31/251) P < 0.05. Episodes of severe hypoxia (SpO2 < 80% over 10 seconds) were more frequent in the control group (8/51) compared with the intervention group (2/47) P < 0.05.

Recent data have suggested superior safety of cold resection. We aimed to assess the safety of cold compared to traditional (hot) resection for non-ampullary duodenal polyps.\u0000Methods: We performed a systematic review ending in September 2022. The primary outcome of interest was the adverse event (AE) rate for cold compared to hot polyp resection. We reported odds ratios with 95% confidence intervals (CIs). Secondary outcomes included rates of polyp recurrence and post-polypectomy syndrome. We assessed publication bias with the classic fail-safe test and used forest plots to report pooled effect estimates. We assessed heterogeneity using I2 index.\u0000Results: Our systematic review identified 1,215 unique citations. 8 of these met inclusion criteria, 7 of which were published manuscripts and 1 of which was a recent meeting abstract.

However, the endoscopic distinctions between the two categories, microvesicular HP (MVHP) and goblet cell-rich HP (GCHP) are not well understood. Therefore, we compared the endoscopic features of SSL, MVHP, and GCHP.\u0000Methods\u0000This retrospective, cross-sectional study was conducted at the Toyoshima Endoscopy Clinic. We examined the polyp size, location, Paris classification type, mucus cap, indistinct border, expanded crypt opening, varicose microvascular vessels, and JNET classification type. Multivariable analysis of each endoscopic finding using a binomial logistic regression model determined the factors that predicted SP histology.\u0000Results\u0000A total of 670 SPs were enrolled in this study, comprising 159 SSLs, 361 MVHPs, and 150 GCHPs. On comparing the SSL + MVHP group and GCHP, a mucus cap (partial regression coefficient 1.705), expanded crypt opening (1.828), and varicose microvascular vessels (1.270) were more often observed in SSL + MVHP group compared with GCHP. In the comparison between MVHP and GCHP, a mucus cap (1.564), expanded crypt opening (1.802), and varicose microvascular vessels (1.288) were more often found in MVHP in contrast to GCHP. When comparing SSL and MVHP, SSLs were more likely to be in the proximal colon (0.662) and were larger (0.198) than MVHPs. No significant differences were observed in other endoscopic findings.\u0000Conclusions\u0000SSL and MVHP have endoscopic appearances that differ from those of GCHP. Considering MVHP and GCHP as distinct entities may aid in the endoscopic diagnosis of SPs.\u0000","PeriodicalId":508938,"journal":{"name":"Endoscopy International Open","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140729318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
